← HistoryWhich outcome results from improperly calibrated artificial horizon mirrors during sextant celestial navigation?
A)Systematic altitude measurement errors occur✓
B)Bearing calculations become near impossible
C)Chronometer accuracy rapidly decreases afterwards
D)Deck flooding risk increases negligibly
💡 Explanation
Systematic altitude measurement errors occur because index error introduces angular offsets during measurement; this is an additive error across all sights. Therefore, observed altitudes are consistently skewed, rather than affecting bearings or the chronometer.
